WW2 German Minesweeper War Badge. Unknown Maker.

This zinc manufactured example has under 50% of its gold finish to the wreath and eagle, the central water plume has close to 100% silver finish including all its black lines to the waves. Detail to the design is sharp. The rear has its period crimped ball hinge and crimped bottom catch. The back has close to 100% of its silver finish. Going by the design and rear hardware this matches close to a ''Adolf Scholze'' manufactured award but i don't believe this is 100% proven.
